These 'altered books' are beautiful sculptures by Portland-based artists Andrew Hayes who uses metal to transform re-purposed books into incredible works of art. In his own words: "The pages allow me to achieve a form, surface, and texture that are appealing to me. The book as an object is full of fact and story. I take my sensory appreciation for the book as a material and employ the use of metal to create a new form, and hopefully a new story."
